    Anyone have a list to break the codes stamped on GM truck axles esp early thru mid 80's.

    Here is a code RHM G 230 1

    Any help here.
    I would really like a complete list the comarro guys have one why don't the truck guys have one?

    i show an rhm for an '82 rear axle w/a 4.10.
    so RHM would seem to be 4.10 gears. G would be the source code which is "Gear and Axle". "C" is Buffalo, "K" is GM of Canada and "W" is Warren. 230 is the day in the year it was made, which would be around the 20th of August of '82. and "1" is the shift it was made on. The first shift.

    this is from a '79-84 GM parts catalog. hope it works for you.
